Self-cleaning suction device

ABSTRACT

A self-cleaning suction device has a user&#39;s suction end that self-sanitizes externally and internally before and after use, as well as self-sanitizes internally during use. A cover opens to reveal the user&#39;s suction end within a containment unit. As the cover opens, the suction end travels from a lower chamber, proceeds through a middle chamber of a sanitizing agent, and is presented for use. After suction is complete, the suction end retracts through an upper chamber with, a scraping feature that removes debris from the outer surface of the mouthpiece, and proceeds down through the middle chamber of a sanitizing agent and a scraping feature that removes debris and the sanitizing agent from the outer surface of the user&#39;s suction end. Upon the sealing closure of the cover, the upper and middle chambers are flushed with a sanitizing agent, which is suctioned away along with any collected debris. The user&#39;s suction end resides within a lower chamber and can be decontaminated by a UV-C light entering into the lower chamber and/or corresponding chambers. The suction device can also include a liquid-hydration delivery system.

BACKGROUND OF THE INVENTION

Suctioning devices are routinely used in the medical and dental fields,as well as in personal use settings, to remove unnecessary or wastefluids. Often such devices are used in conjunction with a surgicalprocedure where it is important to maintain a clean and sanitaryenvironment. Removal of, for example, spittle or drainage from the siteof a wisdom tooth extraction promotes healing and prevents the socketsfrom becoming infected. Periodically sanitizing/disinfecting and/orrinsing the affected area, enhances recovery from the surgicalprocedure. In a lab setting, neutralizing a spilled infectious and/ortoxic compound, as it is being suctioned up, could greatly enhancesafety. In a mobile, personal setting, it may be necessary to suctiondrool, due to an excessive drooling disorder.

Many suction devices have been described and focus on the importance ofisolating the suctioned matter from the patient, user and/or the staffcharged with disposing of it (see, for example; U.S. Published PatentApplication Nos. 2004/0045980 A1; 2004/0072122 A1; 2005/0127103 A1; and2006/0093990 A1; and U.S. Pat. Nos. 3,527,219; 4,966,580; 5,980,498;5,104,315; 5,365,624; 5,984,145; 6,152,733; 6,314,960; 6,358,237;6,409,048; 6,652,481; 6,851,275; 7,007,502; 7,059,852; and 7,118,377).These many devices are large and cumbersome and are designed to be usedby physicians and dentists in an office setting. To maintain a cleanenvironment at, for example, a surgical site, it is important that thesuctioning end, be cleaned and sanitized before and after each use.Although self-cleaning devices have been described (see, for example,U.S. Published Patent Application No. 2005/0187528 A1), these devices donot necessarily focus on cleaning, sanitizing and/or disinfecting thesuction tube end that contacts the surface to be suctioned before orafter use. Further, they do not focus on sanitizing and/or neutralizingthe suctioned matter directly after it enters the suction tube duringuse. The main focus of these devices is treating the suctioned matterafter use and/or at the time it is collected.

A need remains for a simple, adaptable suction device, perhaps enhancedwith a liquid-hydration and/or medicament delivery device, thatfunctions with the user's safety in mind. Recent heightened concern ofbacteria and airborne viruses, only adds to the sanitary necessity, ofsimply and automatically protecting yourself and/or patients, at thesite of liquid delivery and suctioning.

All patents, patent applications, provisional patent applications andpublications referred to or cited herein, are incorporated by referencein their entirety to the extent they are not inconsistent with theteachings of the specification.

BRIEF SUMMARY OF THE INVENTION

The invention is a suction device with a specialized, self-cleaninguser's suction end. The interior of the user's suction end and suctiontube are sanitized/neutralized during suction use. The interior andexterior of the user's suction end and interior of the suction tube aresanitized/neutralized before and after suction use.

A cover enclosing the user's suction end opens, to allow the user'ssuction end to emerge from a lower decontamination chamber, throughsanitizing/neutralizing agents within a middle chamber, through an upperchamber, and to the user for suction use. After use, the user's suctionend retracts through the upper chamber, encountering a narrowing, whichscraps and collects material from the exterior of the user's suction endas it passes. During the course of the user's suction end rising andretracting through the middle chamber, its exterior is cleaned by meansof cleaning seals, and sanitized by means of sanitizing/neutralizingagents isolated within the middle chamber. Once the cover seals closed,the upper and middle chambers are flushed with sanitizing/neutralizingagents, which are introduced into the upper and middle chamber byindependent flow tubes. The sanitizing/neutralizing agents and collecteddebris are suctioned away. The user's suction end resides between uses,within the lower chamber, which enables the decontamination of theuser's suction end by means of, for example, an UV-C germicidal light.

The suction device of the subject invention can include aliquid-hydration delivery device. The liquid-hydration delivery device,is incorporated into the device with a specialized mouthpiece whichdelivers one or more liquid-hydration and/or medicament choices to theuser. Used, as well as new, sanitizing/neutralizing agents and/orliquid-hydration fluids, suction debris, and means to cause suction andsanitizing/neutralizing agents and/or liquid-hydration fluids to flow,are housed within a connected base unit.

DETAILED DESCRIPTION OF THE INVENTION

The invention is a suction device with a unique user's suction end thatis self-cleaning and self-sanitizing externally and internally beforeand after use, as well as self-sanitizing and/or neutralizing internallyduring use. The suction device can additionally be embodied with aliquid-hydration delivery device. The device of the subject inventioncomprises a base unit to provide suction/hydration for an attached handheld device which encloses the self-cleaning user's suction end.

The base unit of the device of the subject invention comprises at leastone pump to create suction. Enabling suction within the enclosed chamberis accomplished either actively by a pump, and/or passively through airinlets in the containment unit of the hand held device and/or by meansof air flow tubes from the base unit. The base unit further comprises asanitizing/neutralizing reservoir and a waste reservoir. Means to emptythe waste reservoir can include a simple drain plug to empty thereservoir by gravity, a pump or removable/disposable bags and/orcontainers. Means to refill the sanitizing/neutralizing reservoir can beaccomplished by a refill spout and/or a removable/disposable insert.Additional pumps can be present in the base unit to provide power todeliver sanitizing/neutralizing agents to the containment unit. In apreferred embodiment, the base unit has a programmable controlmotherboard and corresponding components, allowing parameters such assuction time, suction pressure, sanitizing/neutralizing agent flow,volume and/or pressure, liquid-hydration delivery flow, volume and/orpressure to be controlled. All corresponding components may, for examplebe encompassed with check flow valves/flaps, flow/pressure sensorsand/or liquid level sensors, a heating and/or cooling embodiments, anaudio receiver and/or transmitter, GPS, remote control, and lightssignaling functions/warnings/night use. The corresponding components canbe powered by outlet, batteries and/or solar energy.

Preferred embodiments of a suction base unit 101 shown in FIG. 1, asuction-liquid/hydration base unit 104 shown in FIG. 33, and aliquid/hydration base unit shown in FIG. 37 have correspondingcomponents that are similarly numbered.

Specifically, preferred embodiments of the base units have a systemcontrol panel 108 (FIG. 1) adapted to a system control mother board 112(FIG. 33), which has a universal serial bus (USB) port 111, a flashdrive 113 and corresponding components, to enable manual and/orpreprogrammed system function control. The subject device can bepreprogrammed and/or controlled at the hand held device, the base unitand/or remotely, from a distant location to accommodate a specificuser's needs.

Preferably, the base units have a password and/or manual (male) lockout110 (FIG. 1), corresponding to a password and/or manual (female) lockout110A (FIG. 33), to enable limited access within the base unit and/orremoval of corresponding components. The base unit cover 109 (FIG. 1)opens and is removable along with a connected side cover (not shown) inFIG. 33.

In a preferred embodiment, systems are equipped with heat wires 160(FIG. 36) and corresponding components to enable control of thetemperature of the suction tube 103, flow tubes and hand held device.

A power source unit 121 (FIG. 33) provides solar and/orrechargeable/reusable battery power, and can provide power for a remotecontrol 123 (FIG. 33) to establish communication between the base unitand the hand held device.

Base units can further comprise liquid level sensors, pressure sensors,suction tubes and corresponding pumps, air and liquid flow tubes andcorresponding pumps, a purging tubes, audio ear plug in, air filters,ultra violet lights, check valves and/or flaps and holding containers.

Since it is intended for patient use, the base unit of the subjectinvention is preferably lightweight and portable, the base unit howevercan be larger and stationary if positioned for use in a hospital ordentist's office. It would be advantageous if the device was easilyadapted for use by a number of users. Device parts can be modular anddisposable to allow the device to be sent home with a recoveringpatient, used by the patient until treatment is no longer necessary,returned, reconfigured, and sent home with another patient. A separationof components design, works in harmony with an air flow purging systemto enhance the removal of select components. A removable shell and/orglove on the body, not affecting function, can be easily disposed ofwhen the patient returns the machine. Additionally, all parts of thebody and perhaps the base unit and corresponding components, can beconstructed of materials that can be sterilized by autoclaving and/ormade of an antimicrobial material. Further, treating the interior oftubing and containers with a shedding compound would create anon-adhesive environment to facilitate internal cleaning.

The hand held devices of the self-cleaning suction devices of thesubject invention are connected to the base units by a suction tube 103,power/signal source wires 139, multiple flow tubes 107 and preferably ananti-kink coiled wire 118. The anti-kink coiled wire 118 decreases oreliminates the kinking of connected components during use.

The hand held devices of the suction devices of the subject inventionhave a body, a cover, and a sliding suction tube containment unitcomprising a suction tube, a user's suction end, flow tubes, an upperand middle sanitizing/neutralizing chamber, and a lower decontaminationchamber. In a preferred embodiment, the cover is opened to activateemergence and presentation of the user's suction end at the head of thecontainment unit. Opening the cover can be accomplished by simplesliding the cover out of place, using a button mechanism, or it can beopened remotely, from, for example, the base unit. In a particularlypreferred embodiment, the cover is bifurcated separated down a centerline and pivots away from the center to reveal the emerging user'ssuction end. Applicant notes the cover is a convenient means to signalthe user that the unit is being configured for use. The cover also keepsdust, dirt, and debris away from the enclosed user's suction end and thearea from which it emerges. If however the user's suction end protrudessuch that suction of the area can be accomplished with only the user'ssuction end, the cover may not be necessary since the user's suction endretracts completely within the hand held device.

The hand held device comprises one or more chambers. In a preferredembodiment, an upper chamber, nearer the head of the hand held device,collects debris from the exterior of the user's suction end, as theuser's suction end retracts for storage. The user's suction end passes anarrowing between the upper and middle chambers which scraps/collectsdebris from the exterior of the retracting user's suction end. Thisscraping feature can be enhanced by altering the shape of the narrowing,or providing a resilient sweep around the narrowed section. During thecourse of the user's suction end rising/retracting through thisnarrowing and a narrowing between a middle and lower chamber, asanitizing agents isolated within the middle chamber sanitizes theexterior of the rising/retracting suction end. In a preferredembodiment, the upper and middle chamber flush with asanitizing/neutralizing agents upon the automatic closing of the cover.In the exemplified embodiment, this is accomplished with delivery flowtubes coordinating with pumps within the base unit. The flow tubes runwithin the body of the hand held device. The flushing sanitizing agents,the isolated sanitizing agents and the collected debris, within theupper and middle chambers, are suctioned away by the user's suction end.Suction within the enclosed environment of the upper and/or middlechambers is accomplished by means of passive and/or pumped air enteringinto the enclosed chambers. In an additional exemplified embodiment,sanitizing/neutralizing agents can be deposited into the interior of theuser's suction end, and/or corresponding suction tube, during suctionuse as well as before and after suction use. This is accomplished bymeans of flow tubes which enter into flow channels within the walls ofthe suctioning user's suction end and/or suctioning tube. The user'ssuction end resides between uses, within the lower decontaminationchamber, which is subjected to decontamination, and in the exemplifiedembodiment, an ultraviolet (UV) light.

Additional decontamination features can include the positioning ofultraviolet (UV) light shining into the chambers of the hand held deviceand the liquid containment containers in the base unit.

The hand held device holds the user's suction end, flow tubes, chambersand corresponding components within the body. Preferably, the body isconfigured to facilitate grip and user control. It can have anattachable tilting mechanism and/or be incorporated onto a robotic arm.Activation can be controlled from a base unit, or buttons can be placedon the body for easy access. The body can also be supplied with avariety of, rings, straps, bands, an attachable necklace and/or pullstring to facilitate grip or secure the body to the user if the user isunable to control the body unassisted. The body can be configured with avariety of removable shapes and sizes of for example; grips, covers andbody shells to enhance function ability as well as to accommodate forusers who are physically challenged and/or impaired.

The suction hand held device 102 (FIG. 1), and thesuction-liquid/hydration hand held device 106 (FIG. 30), can be equippedwith an audio transmitter/receiver 219 (FIG. 3), system functionindicators and indicator/warning lights 214, 222, 223 and 224 (FIG. 2),function control pressure switches 222A and 223A, and vibrating abilityproviding a reminder of function needs.

Preferred and necessary components of the hand held devices of thesubject invention having suction functions are described below.Activation for suction use can be initiated by simultaneously pressingactivation pressure switch 168 and safety pressure switch 168A (FIG. 2).A sliding suction tube 154 rises up to the user from a suction hand helddevice 102 (FIG. 2), or a suction-liquid/hydration hand held device 106(FIG. 31) enabling suction use by the user. Upon deactivation, thesliding suction tube 154 automatically retracts, into an enclosedenvironment.

FIGS. 9-15 show preferred embodiments of the sliding suction tubecontainment unit and its operation within the hand held device. Thesliding suction tube 154 rises and retracts on stationary hollow openended ridged suction tube 198 and stationary ridged flow tubes 207(FIGS. 14 and 15). The tip end of the sliding suction tube 154preferably has an anti-suction notch 200 (FIG. 15), to decrease and/oreliminate the sliding suction tube's 154 adherence to the surface beingsuctioned. A slot or hole in the side of the sliding suction tube 154,ridged suction tube 198 or suction tube 103, would likewise decreaseadherence and can be used in combination with notch 200.

The sliding suction tube 154 upper tip end and anti-suction notch 200resides within the cleaning seal 205 (FIG. 10), isolating the slidingsuction tube 154 before and after use within the lower chamber 203 (FIG.9) and isolating the lower chamber 203 from the middle chamber 202.

To equalize the pressure created by the upper portion of the slidingsuction tube 154 rising from and retracting into the isolated lowerchamber 203 (FIGS. 15 and 9), the lower chamber 203 comprises an airpressure equalizer channel 181 (FIG. 11) which travels from the interiorof the lower chamber 203 and enters (not shown) into the passive airfiltering chamber 174 (FIGS. 9 and 17), allowing filtered air to enterand to leave lower chamber 203 equalizing the air pressure within.

The guide channel 197 (FIG. 12) is an example of a notch or channel thatcan be placed in the side of the sliding suction tube 154. The guidechannel 197 travels up and down on a channel guide 196 (FIG. 11). Acorresponding guide channel located (not shown) on the opposite side ofthe sliding suction tube 154 likewise travels up and down on acorresponding channel guide (FIG. 9). In the exemplified embodiment,channel guides 196 are connected to the interior walls of lower chamber203 (FIG. 11). The stability of the sliding suction tube 154 duringmovement is enhanced by the guide channels 197 traveling up and down onthe channel guides 196. One skilled in the art would realize a number ofmethods of stabilizing the rising and retracting suction tube.

In the exemplified embodiment, the raising and lowering of the slidingsuction tube 154 is accomplished by the teeth of the gear 193 rotatingwithin the teeth and/or grooves in the lower portion of the slidingsuction tube 154. The gear 193 located within the lower chamber 203(FIGS. 9 and 15) is connected to gear 195 located on the outside of thelower chamber 203 (FIGS. 9 and 15) by means of a connected axel whichtravels through the side of the lower chamber 203. The axle rotateswithin the opposite interior wall. The teeth of the gear 195 set downinto the teeth of the gear 215 to enable the removal and/or replacementof the containment unit 153 (FIGS. 9 and 15) from within the body (FIGS.15 and 18). Gear 195 is rotated by gear 215, which in turn is powered bymotor 216. The motor 216 is powered by a power source in the hand helddevice, for example, battery 220 (FIG. 15) or a power source 121 locatedin the base unit (FIG. 33). One skilled in the art would realize thereare a number of methods to manually and/or mechanically raise and/orlower the sliding suction tube 154 within the hand held device. Thesliding suction tube 154 can, for example, rise and retract by multiplegears on the facing side and/or rear side of the sliding suction tube154.

The shape and/or size of the sliding suction tube 154 and/or suctiontube can be adapted to accommodate to the specific needs of the user,for example, corresponding components can conform to the size/shape of acatheter tube, enabling the suctioning of a tracheotomy.

When activation for suction use is initiated in the suction hand helddevice 102 (FIG. 1) and/or the suction-liquid/hydration hand held device106 (FIG. 30) suction is created at the tip end of the sliding suctiontube 154, by means of a suction pump 116 (FIG. 33). In the exemplifiedembodiment, the suction pump is a peristaltic pump which enables suctionthrough one continual suction tube. The suctioned matter travels acourse through the sliding suction tube 154 tip end, the suction tube103 and into a contaminant collection container 136. The contaminantcollection container has a filtered air outlet with a check valve orflap, an ultra violet light, and a removable cover with a cover latch124. The contaminant collection container 136 can be emptied by removinga plug and disposing of the material properly, or the contaminantcollection container can be lined with a replaceable bag which isremoved and disposed of or be a replaceable component.

Suction within the enclosed environment of the chambers is accomplishedby passive and/or pumped air entering into the chambers. In a preferredexemplified embodiment passive air is incorporated into the suction handheld device 102 (FIG. 1) and the suction-liquid/hydration hand helddevice 106 (FIG. 30) through a passive air cover inlet 172A (FIG. 4).Preferably, the hand held device has ridges or a rise above and belowthe passive air inlet 172A on the containment cover 163 to dissuade thethumb or fingers of the user from blocking air flow into the passive airinlet 172A.

When suction through the sliding suction tube 154 tip end is createdwithin the enclosed upper chamber 201 and middle chamber 202 (FIG. 10),air flow (depicted by arrows in FIG. 7) is drawn in through the passiveair cover inlet 172A, continues through the passive air chamber inlet172B (depicted by arrows in FIG. 8), travels through the passive airchamber 173 (FIG. 9) and is filtered through the passive air filterwithin air filtering chamber 174. This air continues into the passiveair flow connection channel 176, flows within the air flow channel 156(FIG. 17) and up through the upper chamber air inlet 177 (FIG. 10),allowing air flow into enclosed upper chamber 201, through cleaning seal204, into middle chamber 202, and the air travels into the suctioningsliding suction tube 154, and into contaminant collection container 136in the base unit. FIG. 21 shows upper chamber air inlet 177 and flowtubes 134A entering upper chamber 201. The passive air filtering chamber174 and upper chamber air inlet 177 have check valves or flaps allowingair flow in only one direction. Passive air flow in the exemplifiedembodiment can originate within, near and/or between the base unit andthe upper chamber air inlet 177.

Pumped air can be introduced into the hand held device and issimultaneously activated at the initiation of suction within upperchamber 201 and middle chamber 202. In the exemplified embodiment, apump 126 draws air in through filtered inlet 129, and into flow tube126A (FIG. 33). The flow tube 126A can be split into, for example, threeflow tubes 126A prior to exiting the base unit, and travel to the handheld device. The three flow tubes 126A are located between change-outbase plate 148 and seal 146. FIG. 36 shows an exemplified embodiment ofremovable/replaceable components within the base unit and hand helddevice.

FIG. 17 shows the three flow tubes 126A entering air flow channel 156the air flow channel 156 connects into upper chamber air inlet 177. Thepassive air system has one directional flow check valves or flaps,allowing pumped air to travel past the passive air flow connectionchannel 176 (FIG. 17) up through the upper chamber air inlet 177, andinto the upper chamber 201, enabling suction within an enclosedenvironment. The passive and pumped air systems can function together,and in turn enhance air flow through upper chamber air inlet 177 andinto upper chamber 201, middle chamber 202 and the suctioning slidingsuction tube 154 tip end.

The interior user's suction end of the device of the subject inventionis sanitized during use. This is accomplished by introducing asanitizing/neutralizing agent into the suction tube during use. Flow ofsuctioned debris is also enhanced by introduction of thesanitizing/neutralizing agent as the agents assist in moving suctioneddebris through the suction tube.

Sanitizing/neutralizing agents travel from the sanitizing/neutralizingholding container 131 (FIGS. 1 and 33) through flow tube 133A. Pump 141(FIG. 33) moves the agent through the flow tube 141A to the change-outbase 147 and out the change-out base plate 148 (FIGS. 34 and 36). Flowtube 141A can be divided into three separate flow tubes 141A and travelto the hand held device. FIGS. 14 and 15 depict two facing ridged flowtubes 207 and a third ridged flow tube 207 (FIG. 14). The ridged flowtubes 207, travel up and along the side of the ridged suction tube 198.The flow channels 206A within the walls of the sliding suction tube 154(FIG. 13) travel up and down on the ridged flow tubes 207 as the slidingsuction tube 154 rises and retracts. The flow channels 206B continue onup from the flow channels 206A and open into the interior of the slidingsuction tube 154, enabling delivery flow of sanitizing/neutralizingagents into the interior of the sliding suction tube 154, before andafter suction use, as well as during suction use shown by the arrows inFIG. 13.

The exterior circumference of the ridged suction tube 198 and/or theinterior circumference of the sliding suction tube 154, can have seals,for example, o-rings. Likewise, the exterior circumference of the ridgedflow tubes 207 and/or the interior circumference of the flow channels206A can have seals or o-rings.

The suction tube 103 and corresponding components, the ridged suctiontube 198 and the ridged flow tubes 207 are connected to the containmentunit base plate 153A and are removable/replaceable from the containmentunit 153 (FIGS. 14 and 15). The sliding suction tube 154 is removablefrom within the containment unit 153. Openings through the containmentunit base plate 153A correspond to the connection of the sliding suctiontube 154, the ridged suction tube 198 and corresponding components. Theflow tubes, power/signal source wires, and other components connected tothe containment unit base plate 153A plug into their correspondingcomponents located at or within the base of the containment unit 153.The removal of the containment cover 163 (FIG. 7) allows theremoval/replacement of the containment unit 153 (FIG. 17) from withinthe suction hand held device 101 body (FIG. 18) along with andseparately from removable/replaceable corresponding components. Theremoval of the containment cover 163 from the suction-liquid/hydrationhand held device 106 (FIG. 33) likewise allows removal/replacement ofcomponents. One skilled in the art would realize a number of methods ofdisconnecting and reconnecting corresponding components enabling theremoval/replacement of the desired components. The removal/replacementof components is facilitated by purging air through the system prior toremoval/replacement of the desired components. One skilled in the artwould recognize there are a number of methods to purge air through thesubject system.

The sanitizing/neutralizing agents pumped into the suction tube can beof a varied chemical makeup. Multiple pumps can deliver the many agentsthrough separate flow tubes which combine as they exit into thesuctioning sliding suction tube 154. This design would enhance safety ina lab spill cleanup where suctioned toxic matter could be neutralized,by a mixture of neutralizing agents introduced into the interior of thesuctioning suction tube tip end. Providing sanitizing/neutralizing agentto suction tubes can be adapted to current suction tubes and/orsuctioning devices. Flow tubes can be added to deliver the agent intothe interior of the current suction tubes.

The self-cleaning suction device of the subject invention can furthercomprise a liquid/hydration delivery system (FIG. 30). Liquid/hydrationdelivery can be offered through a specialized mouthpiece, enablingliquid deliver to the user, in addition to a suction functioningembodiment.

FIG. 36 shows removable/replaceable components. Theremovable/replaceable components depicted in FIG. 36, correspond to theembodiment of replaceable/removable suction components shown in thesuction device of FIG. 1.

FIG. 11 shows flow tube 134A and 134B entering into lower chamber 203.Flow tube 134A and 134B each divide into two separate flow tubes andtravel up along the interior wall of the lower chamber 203 and intoupper chamber 201 and middle chamber 202. FIG. 10 shows the two flowtubes 134B entering middle chamber 202 while FIG. 21 shows flow tubes134A entering upper chamber 201.

The upper outer edge of upper chamber 201 is connected to and surroundedby chamber housing unit 186 (FIG. 21). The chamber housing unit 186comprises upper chamber 201, middle chamber 202. FIG. 31 shows thesuction-liquid/hydration hand held device in suctioning mode. FIG. 32shows the suction-liquid/hydration hand held device in a non-suctioningmode.

Before and after suction use in relation to the suction hand held device102 and/or the suction-liquid/hydration hand held device 106, thesliding suction tube 154 tip end and corresponding anti-suction notch200 reside within a cleaning seal 205 shown in FIG. 10. Looking downthrough the upper chamber 201 in FIG. 21 sliding suction tube 154 issurrounded and resides within the cleaning seal 205 which is located atthe bottom of the middle chamber 202 shown in FIG. 10. This enableslower chamber 203 to be isolated from middle chamber 202. The hand helddevice component body 102A has a ultra-violet light 183 (FIG. 18).

The containment unit 153 has a solid clear ultra-violet light window 182(FIG. 17). Ultra-violet light 183 shines through the ultra-violet lightwindow 182 and into containment unit 153 decontaminating the slidingsuction tube 154, lower chamber 203, middle chamber 202, upper chamber201 and corresponding components within the containment unit 153.Preferably, the components within the containment unit are exposed tothe ultra-violet light before and after suctioning by the user.

In a particularly preferred embodiment, the interior walls of the lowerchamber 203 have a reflective quality, wherein the ultra-violet lightentering the lower chamber 203 is reflected throughout the containmentunit. The middle chamber 202, upper chamber 201, cleaning seal 205,cleaning seal 204 are composed of a material that allows ultra-violetlight to shine through. The ultra-violet light is preferably a UV-Cgermicidal light.

Although the use of a germicidal light is preferred to sanitizecomponents of the self-cleaning suction device of the subject invention,one skilled in the art would recognize there are a number of methods bywhich these components can be decontaminated.

Sanitizing/neutralizing agents enter the upper chamber 201 and middlechamber 202 through flow tubes 134A and flow tubes 134B flushing upperchamber 201 and middle chamber 202 and traveling through the slidingsuction tube 154 tip end to the contaminant collection container 136(FIGS. 10 and 33).

The suctioning sliding suction tube 154 rises from within the cleaningseal 205 and into the middle chamber 202. As the suctioning slidingsuction tube 154 enter into the cleaning seal 204 (FIG. 10), thesanitizing/neutralizing agents entering into middle chamber 202 throughflow tubes 134B and the sanitizing/neutralizing agents entering intoupper chamber 201 through the flow tubes 134A ceases. Thesanitizing/neutralizing agent remaining within middle chamber 202 isisolated from lower chamber 203 cleaning seal 205 and is isolated fromupper chamber 201 by cleaning seal 204. The exterior of the suctioningsliding suction tube 154 is sanitized as the suctioning sliding suctiontube 154 passes through the sanitizing/neutralizing agents isolatedwithin middle chamber 202. The cleaning seal 204 scrapes thesanitizing/neutralizing agents from the exterior of the risingsuctioning sliding suction tube 154. The sliding suction tube 154suctions the remaining sanitizing/neutralizing agents from within upperchamber 201. The sliding suction tube 154 rises up through the upperchamber 201 and passes the synchronized opening left cover 184 and rightcover 185 of the suction hand held device 102 (FIG. 2) or the openedcover 155 of the suction liquid/hydration hand held device 106 (FIG.31), and is presented for suctioning use.

Upon deactivation by release of activation pressure switch 168 andsafety pressure switch 168A suctioning sliding suction tube 154retracts. The exterior of the suctioning sliding suction tube 154 issanitized/neutralized as it retracts through the sanitizing/neutralizingagents isolated in middle chamber 203.

As the tip end of the retracting suctioning sliding suction tube 154passes through the opening of chamber housing unit 186 (FIG. 21), andinto upper chamber 201, left cover 184 and right cover 185 (or cover155) seal around the opening and chamber housing unit 186 as suctioncontinues.

Flow tubes 134A (FIG. 10) deliver a continual flow ofsanitizing/neutralizing agent into sealed upper chamber 201, the slidingsuction tube 154 suctions away the sanitizing/neutralizing agents andthe foreign debris collected by cleaning seal 204. The cleaning seal 204collects debris and foreign matter from the exterior of the suctioningsliding suction tube 154 as it retracts through upper chamber 201.

As the retracting suctioning sliding suction tube 154 tip end withanti-suction notch 200 travels through middle chamber 202, flow tubes134B (FIG. 10) deliver a continual flow of sanitizing/neutralizing agentinto middle chamber 202. The sanitizing/neutralizing agent is suctionedthrough the anti-suction notch 200 which enhances debris removal withinthe notch. Sanitizing/neutralizing agents are suctioned from middlechamber 202 and upper chamber 201. Sliding suction tube 154 tip endretracts into and resides within cleaning seal 205 and flow ofsanitizing/neutralizing agents into upper chamber 201 and middle chamber202 ceases. The sliding suction tube 154 tip end suctions away thesanitizing/neutralizing agents remaining within the upper chamber 201and the middle chamber 202 and the corresponding debris collected bycleaning seal 205 and cleaning seal 204 to contaminant collectioncontainer 136 (FIGS. 1, 30 and 33) and suction ceases.

Applicant notes variable liquid flow direction into upper chamber 201and/or middle chamber 202, in combination with, for example, a steamand/or spray would enhance the removal of debris. Further, multiplesanitizing/neutralizing holding containers in combination with multiplepumps would allow a variety of sanitizing, neutralizing, cleaning and/orflushing agents, to flow through separate independent flow tubes, andenter separately into upper chamber 201, middle chamber 202, and/or amultiple of sanitizing/neutralizing chambers.

The sanitizing/neutralizing holding container 131 shown in FIGS. 1 and33 has a check valve/flap at filtered air inlet 130, an ultra-violetlight 140, a liquid level sensor 135, and a removable cover latch 124and flow tube 133A.

Contaminant collection container 136 (FIGS. 1 and 33), has a checkvalve/flap at filtered air outlet 125, an ultra-violet light 140, aliquid level sensor 135, a removable cover, bag insert within, and aremovable suction tube 103. FIG. 33 is also shows a purging tube 145 toenable the liquid/hydration capabilities of the device shown in FIG. 33.

The function pressure switches 222 and 223A allow user control of anumber of functions including, but not limited to, suction pressure, therising/retracting of sliding suction tube 154, suction duration,disablement of the activation pressure switch 168 and safety pressureswitch 168A, increasing/decreasing the sanitizing/neutralizing flowwithin the interior of sliding suction tube 154 during suction use andwhen applicable liquid/hydration capabilities.

Preferably, the hand held devices of the subject invention have coversthat open automatically to enable the suction tube to rise and bepresented for suction use by the user and close automatically when thesuction tube retracts after suctioning use.

In a preferred embodiment, the covers open and close automatically bymechanical means. Gear cover 192 (FIG. 8) covers gear 190 and gear 191(FIG. 15). Gear 190 and gear 191 rotate on axles connected tocontainment unit 153. In this embodiment, the cover has two pieces thatseparate at the centerline to reveal the user's suction end. Thisembodiment is best shown in FIGS. 19-29. Coordinating gears 190 and 191(FIG. 8) reside behind gear cover 192 and allow the cover pieces to opensynchronously. Each gear engages and turns a geared end 184B, 185B onthe end of a rotational cylinder 184A, 185A on one end of each coverpiece 184, 185. Each rotational cylinder sits within a notched housing188, 189, respectively. Gears 190 and 191 engage geared ends 184B and185B to open the cover. Gears 190 and 191 are turned by gear 217 (FIG.15).

The teeth of gear 190, set down into and align with the teeth of gear217. Gear 217 can rotate by a motor located directly below gear 217powered by power source 220 or a power source within or near the baseunit 101. In a preferred embodiment, teeth of gear 190 and gear 217 areangled. The angled teeth make removal/replacement these componentseasier.

A seal 187 lies on the underside of the left cover 185 and the rightcover 184 (FIG. 20). The seal 187 encircling the outer edges of upperchamber 201 when the left cover 184 and the right cover 185 are closed(FIG. 10).

In another preferred embodiment, the suction liquid/hydration hand helddevice has one cover 155. The cover 155 (FIG. 31) has a connected (notshown) rotation cylinder with a geared end which rotates within arotation housing enabling cover 155 to rotate open (FIG. 31) and close(FIG. 30) by movement of the gear 217 rotating gear 190 and gear 191.The cover 155 also has a circular seal (not shown) encircling upperchamber 201.

FIGS. 52 through 62 show another preferred embodiment of a suctioncover. In this embodiment, the sliding suction tube 154 pushes the coveropen as it rises for use. Left cover 265 and right cover 266 part toexpose the user's suction end. A left rotation cylinder 267 on the leftcover 265 rotates within a left rotation cylinder enclosure 271. Thecenter section of the rotation cylinder enclosure 271 (FIG. 57)encircles the center section of the rotation cylinder 267 and engages aslot above the center of the rotation cylinder 267 (FIG. 56). The risingtube encounters push flaps 269 and 270 that move the cover. Thecorresponding opposite ends of the left rotation cylinder 267 and theright rotation cylinder 268 reside and rotate within the opposite endsections of the corresponding left rotation cylinder enclosure 171 andcorresponding right rotation cylinder enclosure 172, enabling both coverpieces to rotate in unison and expose the rising user's suction tip end.

Push flap 269 and push flap 270 remain within the push flaps housing 273before suctioning use (FIG. 52) as well as during suctioning as depictedwithin FIG. 53. Half circular seals 187 connected to the underside ofeach corresponding left cover 265 and right cover 266 seal around thecircular opening located within the top of the push flaps housing 273(FIG. 58), when the left cover 265 and right cover 266 are closed. Thesliding suction tube 154 rises and retracts through the circular openingwithin the top of the push flaps housing 273.

Operably connected tension springs 260 end portions of left rotationcylinder 267 and right rotation cylinder 268 open under tension andclose under tension as the sliding suction tube 154 rises and retracts.

In addition to providing suction, the device of the subject inventioncan include a liquid-hydration delivery device. At least one deliverytube to the liquid-hydration delivery device mouthpiece delivershydrating fluids such as water, or sports drinks. Alternatively, thedelivery tube can deliver medicaments. Further, should the area beingsuctioned need to be flushed, a flushing solution, such as saline,hydrogen peroxide, or mouthwash, could be delivered by at least onedelivery tube. Delivery of fluids to the mouthpiece can be orally drawnup and/or powered by, for example, a pressurized system or pumps. In apreferred embodiment the liquid-hydration delivery device isincorporated with a specialized mouthpiece. In an exemplifiedembodiment, multiple delivery tubes can be provided to deliver a numberof fluid choices or alternatively, a purging system allows a tube(s) tobe purged of the delivery fluid and replaced by a new fluid. Themouthpiece can be fitted with covers, which can be pushed to the side,removed or manually and/or mechanically opened. The liquid-hydrationdelivery mouthpiece can be included in its own hand held device, or themouthpiece can be included in the hand held device of the suctiondevice.

A liquid/hydration specialized mouthpiece, when pressed down allows auser to receive a liquid, a hydrating fluid, a medicament and/or anutritious substance. A preferred embodiment of the specializedliquid/hydration mouthpiece is shown in FIGS. 50 and 51. FIG. 50 showsthe specialized liquid/hydration mouthpiece in a “non-use” (no-flow)mode. FIG. 51 shows the specialized liquid/hydration mouthpiece in an“in-use” (flow) mode.

The component pieces shown in FIGS. 47, 48, and 49 interlock to form thespecialized liquid/hydration mouthpiece. FIG. 49 shows tube capsule unit246 and spring enclosure 250A connected to the tube capsule unit base246B. Tube capsule unit 246 is a circular hollow cylinder. FIG. 48 showsmouthpiece slide unit 245. The mouthpiece slide unit 245 is a hollowopen ended cylinder, formed in shape and size to slide onto tube capsulebase unit (FIG. 49). FIG. 49 also shows air channel guide slot 208B andthe power connect guide slot 208A located in spring enclosure 250A. Thepower connect flange 245A is connected to the mouthpiece slide unit 245as shown in FIGS. 45 and 48. The power connect guide slot 208A, is anopening through spring enclosure 250A (FIG. 45). The power connectflange 245A travels through the spring enclosure in power connect guideslot 208A and rests on spring 250. It is pressed up under spring tensionagainst the top of power connect guide slot 208A. An opposing view ofFIG. 45 (not shown) would show air chamber flange 245B traveling throughthe air channel guide slot 208B and resting under spring tension onspring 250 and pressed up against the top of the air channel guide slot208B.

Continual spring tension on the bottom side of the mouthpiece slide unit245 causes the mouthpiece slide unit 245 to remain pressed up impedingflow and closing the mouthpiece to flow. The spring tension also causesthe mouthpiece slide unit 245 to return to the no flow position whenpressure on the mouthpiece cap 212 is released.

FIG. 47 shows mouthpiece cap 212. The mouthpiece cap 212 has a honeycomb247, honeycomb housing 248, honeycomb base plate 249, seals 199,mouthpiece cap flange 212A and threads 212B. FIG. 46 is a top sidefacing view of the mouthpiece cap 212 and shows the cylindricalcomponent.

The honeycomb housing 248 is a hollow cylinder shaped component withseals 199 circling the outer circumference of the honeycomb housing 248.The pie-shaped honeycomb 247 is connected to the solid honeycomb baseplate 249. The openings of the pie-shaped honeycomb 247 travel throughthe center of the mouthpiece cap 212 (FIG. 46) and open up from betweenthe honeycomb housing 248 and the honeycomb base plate 249. Themouthpiece cap 212 is removable/replaceable so that it can be cleanedand/or replacement with a variety of shapes and sizes of mouthpiece caps212 focusing on the specific needs of the user.

In the exemplified embodiment mouthpiece cap 212 screws onto mouthpieceslide unit 245 by threads 212B. When the mouthpiece cap 212 is screwedonto mouthpiece slide unit 245, the bottom portion of the honeycombhousing 248 and seal 199, the honeycomb 247, and the honeycomb baseplate 249 and seal 199 rotate down into and are surrounded by the hollowcylindrical shape of stop flow housing 246A. This isolates honeycomb 247openings from the interior of the liquid delivery chamber 251 preventingflow.

An air chamber 256 surrounds the tube capsule 246 and exists below themouthpiece slide unit 245 creating an isolated air chamber 256 withinthe mouthpiece. Mouthpiece cap 212 presses down and creates a greatlydiminished air chamber 256 (FIG. 51). Air chamber channels 257 with airfilters 258 in mouthpiece slide unit 245 allow air to flow from and intoair chamber 256.

Liquid delivery to the specialized mouthpiece is accomplished by one ormore flow tubes embodied with check valves or flaps traveling from aconnected container. The specialized mouthpiece can be configured sothat liquid/hydration can be drawn up orally, or be delivered underpressure by pump from a connected container.

To use mouthpiece cap 212 the cap is pressed down, and power connectflange 245A depresses pressure switch 252A activating the power signalunit 252 and signaling the base unit to initiate liquid flow to themouthpiece (FIG. 51). Flow tube 143A with a check valve and/or flapconnects through the tube capsule unit base 246B allowing liquid flowinto liquid delivery chamber 251. Multiple flow tubes allow liquid flowinto liquid delivery chamber 251 (FIG. 36).

In the exemplified embodiments, flow tube 143A draws liquid from aliquid holding container 142A with air filter 127 having check valves orflaps, a UV-C germicidal light 140, a cover release 124, a connectedflow tube 143A and the replaceable bag and/or container within. Pump 143(FIG. 33) when signaled by the mouthpiece cap 212 being pressed down,pumps liquid through flow tube 143A to the liquid/hydration specializedmouthpiece allowing liquid flow through the check valve and/or flap 159,into the liquid delivery chamber 251, through the honeycomb 247 and tothe user (FIG. 51). When mouthpiece cap 212 is pressed down signal unit252 signal the system control motherboard 112 by power/signal sourcewires 139 connected to the base unit. The signal unit 252 is powered bythe battery 220 (FIG. 18) and signals the system control motherboard 112(FIG. 33) by remote control 123 (FIG. 3).

The liquid/hydration specialized mouthpiece is preferably fitted with apurge tube 145 with check valves and/or flaps. The purge tube 145travels from the liquid delivery chamber 251 and empties into acontaminant collection container 136 (FIGS. 33 and 37). When not in useliquid flowing through the flow tube 143A (FIG. 44) enters into theliquid delivery chamber and travels through the one-way check valve/flapof the purge tube 145 to contaminant collection container 136. Flowthrough the flow tube 144A (FIG. 44) flushes out the previous liquidfrom within liquid delivery chamber 251, allowing another liquid choicefor the user. In the event of excessive flow pressure within the liquiddelivery chamber 251 during liquid/hydration use pressure sensitivecheck valve/flap of purge tube 145 would release the excess liquid intopurge tube 145. Check valves and/or flaps are pressure sensitive.

Removing/replacing the mouthpiece cap 212 from the liquid/hydrationspecialized mouthpiece is facilitated by first purging air through theliquid flow tubes, through the liquid delivery chamber 251, through thecheck valve/flap of purge tube 145, and components continuing to thecontaminant collection container.

Full depression of the mouthpiece cap 212 pushes the mouthpiece capflange 212A down to mouthpiece mounting platform 293 (FIG. 51). FIG. 44shows the liquid/hydration specialized mouthpiece connected to amounting platform 293 the mouthpiece is integral with the hand helddevice. In this embodiment the specialized mouthpiece can be enclosedwithin and/or presented for use by a mouthpiece cover 209 (FIG. 31)and/or the left cover 233 and the right cover 234 (FIGS. 38 and 40) canbe configured to be manually and/or mechanically opened and closed.

The liquid/hydration specialized mouthpiece can be used without pressureswitch 252A, power signal unit 252, and power source 139.

The liquid/hydration specialized mouthpiece can be used on any liquidcontainer cap. Flow tubes would travel down from the liquid deliverychamber 251 through the liquid container cap and into the connectedliquid container. The liquid container cap and/or liquid container musthave an air filter check valve and/or flap inlet allowing the user toorally draw up liquid through the liquid/hydration specializedmouthpiece from the corresponding connected liquid container. Further,the liquid/hydration specialized mouthpiece can be fitted with coversthat are pushed to the side or are removable and/or replaceable.

The specialized liquid/hydration mouthpiece shown in FIGS. 38-44 hasfunction control pressure switches and/or a signal indicator lights 237Afacilitating function control by the user. Function control is alsoenabled at the base unit.

To present the specialized liquid/hydration mouthpiece shown in FIGS.38-44, the left push bar 235 and right push bar 236 are pressed in. Aspring plunger 241 connected to left push bar 235 travels within springcasing 242 and condenses a spring 243 to release the cover. Toothed pushrod 240 rotates gear 239 which in turn rotates right gear 239A. Thetoothed push rod 240 is connected to the right push bar 236. The rightgear 239A rotates the right cover gear 234A and the connected rightcover 234 opens. The rotation of the right gear 239A rotates the leftgear 239B which rotates the left cover gear 233A and connected leftcover 233 open revealing the liquid/hydration mouthpiece cap 212presented for use.
